Kabuki Quantum Fighter is an NES game that involves hurling quantum formulas at your opponent.

Just kidding! You actually whip enemies with your luxurious red hair. For reals.

Level Select

To activate a level select, press the following on Controller 2 at the title screen: A (×8), B (×4), Right (×16). When the "ROUND 1 START" screen appears, you can press Up or Down on Controller 1 to select your starting level. There are 256 level numbers to choose from, but everything above C will freeze the game.

This also activates a debug mode of sorts. During game play, Up and Down on Controller 2 can be used to alter the player's chip levels, and pressing A on Controller 2 will skip the level.

Unused Weapon

At the cost of a whopping 16 chip points, this unfinished sixth special weapon sends an orb straight up into the air, creating a rain of glitched projectiles (the red/orange shapes in the right image). This weapon has no associated sound effects, and does not hurt enemies. It may be enabled by setting $00D0 to 07.

C965 Over

This enigmatic screen is stored alongside the GAME OVER and TIME OVER screens, and behaves identically to a TIME OVER when activated. No idea what this could have possibly been used for.

Sound Test

Press B at the end of the credits for a sound test screen. In the US version, Sound Test can be accessed at the game start. When the HAL logo animation stops, press Select + B + Down on Controller 1.

Regional Differences

To do: Specific differences here

The Famicom version is actually a follow-up to the 1990 Japanese film Jipangu (AKA Zipang). The NES version removed a lot of these influences so the game can stand alone as its own work. This includes changing a lot of the closeup graphics and the storyline, although there were other unrelated minor differences as well.
